Summary: We consider numerical methods of solving evolution subdifferential inclusions of nonmonotone type. In the main part of the chapter we apply the Rothe method for a class of second order problems. The method consists in constructing a sequence of piecewise constant and piecewise linear functions being a solution of an approximate problem. Our main result provides a weak convergence of a subsequence to a solution of the exact problem. Under some more restrictive assumptions we obtain also uniqueness of the exact solution and a strong convergence result. Next, for the reference class of problems we apply a semidiscrete Faedo-Galerkin method as well as a fully discrete one. For both methods we present a result on optimal error estimates.
